On tectonics, it wasn't only Bullard and Blackett, it was, famously, J Tuzo Wilson and then Marie Tharp and Bruce Heezen (although I have my doubts about how active Heezen was, apart from he was male and therefore more believed than Tharp, a telling condemnation in itself). There remain a small cadre of geologists in the U.S. who *still* try to refute evidence for tectonics, despite, now, deep seismic imaging of the mantle which reveals descending plates and microquakes along them.
